Filter by:The Tourniquet test is used as a diagnostic procedure for thrombocytopathies and vascular diseases. Currently, there is no evidence whether this test is also positive in hereditary haemorrhagic telangiectasia (HHT), a vasculopathy. The aim of this study was to investigate whether this non-invasive test could also be used as an additional diagnostic criterion in patients with HHT.
Bevacizumab is widely prescribed for the treatment of severe bleeding related to epistaxis or gastrointestinal bleeding in HHT. We studied the efficacy of bevacizumab on severe bleeding in HHT patients in a randomized study recently published (NCT03227263, J Int Med 2023). In this study, 24 patients were included, 12 patients received bevacizumab and 12 patients received placebo. The duration of patient participation was 6 months, including the 2.5-month treatment period and 3.5 month follow-up after treatment. We describe the evolution of the number of RBC transfused in HHT patients who received bevacizumab during the year after the end of the study.
The present project aims to study the inflammatory and endothelial responses involved in the differences in clinical events related to both genotypes (ENG vs. ACVRL1) in HHT. Accordingly, a cross-sectional study is proposed to evaluate the differences in circulating inflammatory and endothelial biomarkers, including interleukines, adhesion molecules, chemokines and immune regulatory molecules between both HHT groups.
The goal of this study is to better understand HHT, the symptoms and complications it causes ("outcomes") and how the disease impacts people's lives. The investigators are aiming to recruit and gather information together in the Registry from 1,000 HHT patients from four HHT Centres of Excellence in North America. The Investigators will collect long-term information about the people in the Registry, allowing the investigators to understand how the disease changes over time, and what factors can influence those changes. Ultimately, this should help improve treatments for the disease.
During the Efficacy Study (Part B), the investigators will study whether Pazopanib, taken daily for 24 weeks, will reduce the severity of nose bleeds in patients with hereditary hemorrhagic telangiectasia (HHT). Patients will either be provided active drug or a placebo [sugar - inactive pill], and be tested for nose bleed severity throughout the trial, including particularly nose bleed duration. Investigators will also test for blood loss, as well as for safety. This study is funded by the US Department of Defense USAMRAA and FDA/OOPD.
This is a randomized, controlled, double-blind, placebo-controlled trial of intranasal Avastin (bevacizumab) injection versus saline control for control of HHT-related epistaxis when used in conjunction with bipolar electrocautery.
In a case series intranasal submucosal bevacizumab has been shown to reduce epistaxis in patients suffering from Hereditary Haemorrhagic Telangiectasia together with KTP Laser therapy. The aim of this study is to evaluate the effectiveness of submucosal intranasal bevacizumab compared to placebo in a randomized double blind trial setting.
